More information than you ever wanted to know about Chrysler paint codes:
Chrysler uses three-character codes for paint. In the "official" method, the first character is a model year code for the first year the color was formally introduced. The second character is the general color description; some examples are as follows: A = argent, B = blue, G = green, J = green, R = red, S = silver, T = tan/brown, and so on. The third character specifies the exact shade/hue of the general color in question. In the old days (late '60s into the '80s), the third character was always a number; the higher the number, the darker the shade. Eventually, they began to also use letters for the last character in order to be able to refer to a wider spectrum of colors.
You'll notice I said the above was the "official" way of referring to paint. However, there is also a slightly more informal method which is used in certain situations (such as on modern build sheets and modern fendertags). In this more informal method, the first character will be either a P or a Q; P indicates the primary color for the vehicle, whereas Q refers to the secondary color for a vehicle with a two-tone paint job. If the vehicle has a monochrome paint scheme, then the last two characters of both informal paint codes will be the same. Thus in this case, PS5 and QS5 are two seemingly-different codes for the exact same color.
For even more verbal shorthand, knowledgeable people will sometimes eliminate the first character entirely during quick/casual conversation. For example:
Customer: "I need some touch-up paint for my '99 Ram 1500."
Parts guy: (opening his 1999 paint catalog) "What color?"
Since there was only one B3 color available for a '99 Ram 1500, this answer is sufficient for the parts guy to know exactly what color the truck is, and thus which touch-up paint the customer needs. Make sense? But there would have been no problem had the customer said PB3 instead.
So there is your explanation. I hope someone out there found it informative.
